Are there any mechanical differences in the 08 LMM Allisons compared to older ones?
Are all actuators the same on my 05 Ally (except for 6th speed obviously)?

I believe the LMM transmission's don't use the input speed sensor to control torque converter lock up.

The 6 speed changed the front rotating drum to a better design and more holding power. Valve body changed slightly also.
